| titleOfInvention | A METHOD FOR THE PREPARATION OF AZETIDIN-2-ONAS. |
| abstract | A method for the preparation of azetidin-2-ones containing a thio-substituent at position 4 of the ring, of formula: ** (See formula) ** where X is halogen, an azido group or an imido group derived from a dicarboxylic acid; R is an alkyl or aralkyl group; R1 is an alkoxy or aralkoxy group; R2 and R3 are the same or different and each represents hydrogen, alkyl, aralkoxy or alkylthioalkyl; Y and Z are both hydrogen and when taken together represent a bond between the carbon atoms to which they are attached, the method of which is to react a thioimidate derivative of an α-amino acid ester with a monosubstituted acetyl halide of the formula I: X.CH.CO.Hal (I) where X is halogen, an azido group or an imido group derived from a dicarboxylic acid and the symbol -Hal- represents halogen, under anhydrous conditions and in the presence of a tertiary base.
